I've set two breakpoints in the source, when I launch the debug session however I see this in the console output: Cannot insert breakpoint 6. Error accessing memory address 0x25a: Input/output error. Cannot insert breakpoint 7. Error accessing memory address 0x8: Input/output error. and my breakpoints are never hit. The application does run however. Any ideas on what the I/O errors mean?

Error In Re-setting Breakpoint 1: Cannot Access Memory At Address
21:55 fred basset 3,1261555108 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted Any ideas on what the I/O errors mean? They mean that GDB (used by Eclipse CDT) tried to set breakpoints on address 0x25a and 0x8, and failed (there is no code at either of the above locations). Why GDB decided to set breakpoints there is impossible to say: you didn't provide any details about how you have set your breakpoints. share|improve this answer answered Jan 2 '13 at 23:44 Employed Russian 86.4k14118171 Thanks for the response. I cleared all my breakpoints then set them again (from within CDT) and they worked this time. No explanation for the previous problems. –fred basset Jan 4 '13 at 22:01 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

Warning Cannot Insert Breakpoint 1
3 All Go Down Author Topic: Problem with Debugger when upgrading MinGW (Read 16857 times) recobb gdb cannot access memory at address Multiple posting newcomer Posts: 30 Problem with Debugger when upgrading MinGW « on: February 10, 2011, 01:46:19 am » I decided to try one of the nightlies (svn 6931) instead of the 10.05/MinGW package I have been using. I installed MinGW from http://sourceforge.net/projects/mingw/files/ using mingw-get-inst-20101030.exe, and put it in a C:\ root folder. I also renamed the MinGW folder in the Codeblocks Program Files http://stackoverflow.com/questions/14129826/eclipse-cdt-error-accessing-memory-address-0x25a-input-output-error folder, and changed my path statement to reflect the new location. I also updated the CB toolchain executable, which, with auto-detect, found the new location.Next, I cleaned my project and rebuilt it. I was able to start the debugger, and it showed the new version number. I can even set breakpoints. However, when it stops at some of the breakpoints (nothing fancy or inline), I cannot single step, as I get an error message about accessing a memory address:Setting http://forums.codeblocks.org/index.php?topic=14193.0 breakpointsDebugger name and version: GNU gdb (GDB) 7.2Child process PID: 3348....At E:\Analysis\wxproj\wxrcplot_data\dataclass.cpp:239Error accessing memory address 0x7816cd30: Input/output error.And I am not able to get any useful debugging after that.So then I changed the name of the C:\mingw root folder, restored the original name of the Code Blocks\MinGW folder, changed the path statement back to the original, and updated the toolchain executable location again. Once again, clean and rebuild. At the same point that I could not debug with the 7.2 version of gdb I was able to with the older 6.8 version. I also checked between the svn and 10.05 version, and there is no problem there - that is, the debugger works in both versions with the older version of MinGW, but not the newer version.I do get an error message with the older version, but it does not seem to impact on functionality (i.e., breakpoints, stepping, watches, etc all seem to work OK):Setting breakpointsDebugger name and version: GNU gdb 6.8Child process PID: 764Error while mapping shared library sections:I don't know how long that error has been there, I never paid much attention to the debugger log when everything seemed to be working.I'm pretty much a newbie at all this - I could just go back to the canned package and use that, but I'd like to learn to play in the sand box with the bigger boys Here's some version info from the two v
